Let's see here.
I'm going to work my way from the top down. Don't want to seem like a hardass, but, I've got a thing about making sure articles meet up to the admin's expectations for being polished when they're still shiny, new, and readily addressable.
For the name, we need a capitalization for a proper noun, there is also a need for a 'family' name which falls between the monicker and caste. Family name is just the same as a surname, it'd be the name shared within the family unit.
Under build and skin color, there is a statement of "with an athletic build, so strong arms and legs with a well-built torso", drop the 'so', it seems out of place. As SageShooter said as well, a mention of the bonded animal would be handy too.
Couple of typographical errors under the psychological characteristics, just re-read it out loud to yourself, that helps the drafting process when something is spoken, serves to bring attention to where a slip-up would have been made.
As SageShooter noted, the mother and father situation is kind of in need of being addressed. Don't forget to capitalize the names for the siblings, and format the header there with **Siblings:**
Capitalize 'fighting' to 'Fighting' under skills. On the topic of the fighting skill, perhaps flesh it out a bit more, indicate what weaponry is being referred to when referring to 'weaponry', it is kind of vague, and could use some brushing up.
Art and Vocations, some capitalization errors, and indicating that 'he had to have it' comes off kind of awkwardly. Perhaps flesh it out as to why he had to have it.
Knowledge, its pretty solid, though, remember we use the American English spelling here, so armour would be armor.
Biology; this one makes him come off as a sadist in the degree of a troublesome child that likes picking on small animals. Don't know if that's what was being aimed for.
Survival; Flesh out what his training entailed perhaps.
In conclusion; the concept is sound, the execution needs to be polished a little, but that aside, just a few corrections to the things mentioned and you're good to start out.
